Symptoms: The melon strips are restricted from expanding from the middle to the top. The tip is more pointed and the melon strip is shorter.
Cause: Insufficient supply of nutrients, high temperatures in the early stages of melon development, or root injury, or lack of fertilizer and water, resulting in obstruction of nutrient and water absorption. Extensive application of chemical fertilizers, soil salt content is too high resulting in high soil solution concentration, inhibit root absorption of nutrients. Excessive watering, excessive soil moisture, and inhibition of root respiration can not produce enough energy, resulting in reduced absorption capacity. Plants have been aging, too many leaves or leaves damaged by pests, stems and leaves too dense, poor ventilation and light transmission, in the case of fertilizer, soil moisture, etc., but also easy to produce sharp mouth melon.
Control methods: reduce the amount of chemical fertilizers, increase the application of organic fertilizers, practice has proved that in the case of organic fertilizer is sufficient, the zucchini will show a good high yield, and only under the conditions of organic fertilizer adequate fertilizer will only play a more effective fertilizer effect it is good. Into the result period, we must do a good job in management of temperature, humidity, light and moisture. Avoid overheating or overheating. Do not flood the area with water. The bigger the melon, the more nutrients it absorbs, so it is important to harvest the melon in time to keep the plants growing.
